To all whom it may concern:

Be it known. that I, JOHN WARD, a:

citizen of theUnited States,1.and a .resi dent of the borough of Manhattan of the city of New York,in the county and State 'of New York, have invented certain new and useful Improvements inVentilatorsfor Railway-Cars, of which the following, is a specification.

The inventlon relates to improvements i11 ventilators for railway cars which aredesigned to suck the air fromzthe interior of the car when the latter is in motion- The inventionparticularly relates todetails of construction dueto which a comparatively large suction is created by means of inwardly and downwardly inclined parts view through the roof portion of 1 a car;

which roof portion. is provided withwvertical walls to which is secured one formof' the ventilator. Fig. 2 is a partial side elevation of the car shown in Fig; 1, the vena tilator being shown: inposition thereupon.

Fig. 3 is a partialside and longitudinalsecs tional view through the ventilator shown i in Figs. 1 and 2.. Fig. 4 isa partial end and transverse sectional view of the ventilator shown in the precedingfiguresr. Fig. 5 is a sectional view of a car having an inclined roof to which is attached another form of ventilator. Fig.1 6 is a side view of the car shown in Fig.5 with a ventilator thereupon,

the ventilator 1 however being jpartially broken away so as toshow the cross section:

of the air delivery portion: thereof taken on the line 6-.6 of Fig. 5. Fig. 7 is an en-; larged viewtaken on the line 66 of Fig.

5. Fig.8 shows another forinof ventilator which may be utilized. In this figure the ventilator has been applied to a car having:

an inclined roof. Fig.9 isa side View of the car shown in Fig; 8, the ventilator in Fig; 9 being partially broken away so as to show: the cross section onthe line 99 of Fig.8.

Fig. 10 is an enlarged view; taken on the line 9-..9 of Fig. ;8.

InFigs. 1 and 2,1 designates the vertical walls of the roof of the car to which is secured the base 2, meaning that portion which is'applicd to the wall or roof of the car and serving as means for holding the ventilator in place thereupon. It Wlll. be observed that the .ventilatonhaving the I cylindrical body portion 3is open: at the bottomand. provided with vertical; walls or flanges 14,. 51and 6 which surround this opening. In the sides or lateral wal1s7and Sthere is provided the opening;7 and 8 for the passage of air as the car moves long the track. The air passing these openings strikesthe inwardly and downwardly extendingportions 7 and 8" which deflect the air toward and through the lower delivery openingof the ventilator. The flanges 5 and 6 that are located at the lower. portion of the inwardly and downwardly inclined side walls cause a suction to be created within lthe ventilatoras. the car moves forward and this suction ismateriolly aided by the airpassing through the opening; 7. or 8, whichis forced inwardly and downwardly and out through the opening at the bottom of the ventilator. I From: an inspection of Fig. 3 it. will be observed that the. openings 17 and 8 and also the inwardly and downwardlyextendingportions 7 and 85 extend substantially the full length ofa the cylindrical body portion 3.

The forms shown in. Figs. 5 and 7 land that shown in Figs. 8 to 10 have both been appliedto a tear having, an inclined roof. It will be observed that in.al1 of the forms 1. above referred to there is a suction PIOdllCr. 1 ing and air delivering portion thatis open at. the bottom or Iunderside and whichuexe tends substantially horizontally. In 7 the forms shown in Figs. 1 to 4 and also in Figs. 5 to 7 the cross section of this air suction and air delivering portion is substantially the same as can be seen from a comparison of Figs. 4: and 7. .In Fig. 5 the air suction and air delivering portion is designated by the reference character 91and in.Figs. 811:0 10 the corresponding air suction and air Ede" I livering portion: of theventilator is designated by the reference character 10.

The opposite ends. of the suction and air delivering member 9 are connected: with the interior of the car by parallel vertical tubes 11 and 11, one of whichiis shorter than the other, dependent uponathe inclination ofthe downwardly extending.

.rality oiitubes at the opposite ends of the suction memberallows a comparatively free passage for the air from the interior of the car to'said suction portionot the ventilator.- These vertical tubes are provided with flanges 12, 1'3", 14: and 15 which serve as means for holdin upon the roof of tidecar. V

In the, form shown in Figs. 5 to 7 the cross, section of the air suctionand'air delivering; portion as above stated is substantially the:

. same as that shown inFigs. 3 and 4. II1E' vFigs. 3 and't andfalso in Figs. 5 and 7 it; will benotedthatth-is air suction and air delivering portion comprises a 'cylind-rical body provided with an opening at the bot tom-or underside thero f which extends substantially 'full' length and it will" alsojbei d notedg'thatthe openings in thesides of this;

cylindric albody" are locatedfin the down-e 1 wardl y approaching portions of the body;

In the form shownin FigsgSto 101the1;

air-{suction and air delivering portion is,

vention.

I clann as my invention:-

1. The combination ofa car roof'an'd a motion the air delivering andsuction creating portion of the ventilator ext-ending.

transversely of-the car'andflthe delivery and of the ventil'ator located' at the underside of theventilator, said delivery end having at the opposite sides of itsdeliveryopening vertically extending-[flanges which are located at the lower endsoffdownwardly 'and inwardly inclined sides, said downwardly longitudinally, the ventilator alsobeingpro- .vided with inwardly and downwardly in-r clinedair deflecting portions for causing the air passing in through said openings, inthe,

sides to move downwardlyand outwardly said air deflecting portions each being integral with vthe material which forms the;

lower portion of one-of the sides.)

2. A ventilator having a 'hollow' cylindrition thereof vertically extending flanges, openings in the lateral walls'of the body and inwardly and downwardly deflecting,

portions to engagethe airpassinginwardly through the "discharge opening there being a direct communication between the airde- *livering means and the interior of the car,

through said openings, said'last mentioned 1 Y defiectingportionsandj said vertioally' extending flanges being) integrally connected with each other.

3. A ventilator comprisingapproaching thereof an air discharge openings. said sides beingprovided with openings topermit air to. pass inwardly, and portions or' members 'between but integral with; said approaching sides, which portions-or, membersfapproach each other and also approach the air discharge I opening'and also being arranged-to deflect the air passingthroughfthe"openingsinthe side's toward the; airdi'scharge opening." 1'

74.. A ventilatorphaving a horizontal, air,

suction and delivering, means; having; the T25 air. delivery opening at theunderpOrtion,

the material whichconstitutes the sides.

5. A ventilator for railway cars having a longitudinally extending hollow cylindrical body provided with an air-delivery opening at the under portion thereof, openings in copies of this patent may be obtainedfor the.lower :part of the side walls thereof and Within said body, deflectingplates which are a partof the side walls and whichplates extend downwardly and approach each other, said deflecting plates being spaced apart and arranged so as to deflect alr passing inwardly through said openings in the said walls out through the air delivery opening.
